Delta Membrane Systems win Property Care Assocation, Property Care Innovation and Sustainability Award 2017

  • 11 May 2017

Delta Membrane Systems Limited are the winners of the Property Care Assocation, Property Care Innovation and Sustainability Award 2017 following work on flood resilience.

Since David J Symes, Technical Director of Delta Membrane Systems Limited, joined a focus group of experts across many disciplines under The Property Flood Resilience Action Plan in 2016, the project has significantly progressed.

The focus group included Stephen Garvin, Director of the BRE Centre for Resilience, Clare Moriarty, Permanent Secretary, DEFRA, Emma Howard Boyd Chair, Environment Agency, Gareth Howell, Managing Director, Direct & Retail Partnership, AXA Insurance and many more. These experts worked together to tackle flooding and flood resilience and combat the devastation caused by flooding.

Delta Membrane Systems Ltd’s Technical Director, David J Symes produced a specification using technology used by Delta Membrane for years.

A scheme was developed utilising a Delta Membrane System’s wall membrane “Delta MS500” and Delta floor membrane “Delta MS20” with a Delta sump and pump system (a Delta Dual V3 sump), with high level alarm “AlertMaxx” and a battery back-up “PowerMaxx”, part of the Delta Maxx family.

With families often left homeless when flood water enters their homes, Delta Membrane is aiming to significantly reduce the time that families are out of their home. 

The Delta membrane is a HDPE extruded sheet that is dimpled and therefore provides an immediate barrier against the effects of salts and contamination caused by water ingress and flood water, allowing fast track reinstatement and allowing the wall to dry out. 

Delta MS20 overlay, also demonstrated in the BRE test house, is a 20mm extruded sheet that can be used on solid floor. The walls and floor have been lined with a cavity drain membrane which provides an air gap.

David suggested that a Delta perimeter drainage channel should be rebated into the floor to make the structure more resilient. Therefore, this deals with ground water which may rise through the floor in the future or through the walls behind the MS500.

The drainage channel collects the water from beneath and behind the membranes and immediately evacuates it to the delta packaged pump station which houses two submersible pumps. Delta can offer pumps that can evacuate as little as 2 litres per second or up to 6 litres per second.

David instructed a standard 110mm pipe to be laid within the slab and turned up 90 degrees to provide drainage outlets to finish flush with the floor finishes, and be located in unobtrusive locations covered with a floor grill.

This was designed to pick up water that may bypass flood gates which should be installed in conjunction with the system and immediately evacuate it reducing damage. 

The Delta system can be installed both into existing properties and in new construction. As with below ground waterproofing, each design is bespoke to the property and each associated risk.

The BRE have successfully demonstrated the resilience and resistance of the flood house. The Flood Resiliance House is a great success and the foundation for incorporating these measures in homes has been laid.
